Three men, Harold Liddle, David Jakiela and Peter Schlette, were killed and four men, Victor Amaro, 41, Robert Eckert, 38, David Maloney, 52, and Paul Smith, 47, were arrested after the late September incident.

It was supposed to be a charity motorcycle ride but the violence interrupted the ride.

Investigators have not disclosed much since the shootings, but said they seized 14 guns and 23 sharp edge weapons at the scene.

Sources said the incident began over a bad feeling between two groups which share the Warlocks name.

In a search warrant receipt filed after the search of a Jeep at the scene, documents indicate the Jeep had two shotguns, two handguns and a bullet proof vest inside it.

The state has until Saturday to file formal charges against the four men arrested.
